SPECIFICATION forming part of Letters Patent No. 708,346, dated September 2, 19'02. Application and May 14, 1902. serial No. 107.296. oro model.)

To all whom it may concern:

Be it known that we, GEORGE H. GEONDIN, SIMON BRILLARD,and JOSEPH L. LABEANCHE, citizens of the United States, residing at Waof Maine, have invented new and useful Improvements in Trucks, of which the following the ground.

The object of the invention is to provide meansfor bracing the 'truck and for locking the same in elevated position'.

, A further object is to employ a device o simple construction whereby the truck may be readily released or unlocked when it is desired to lower the same.

With the above andother objects in view the invention consists in providing a frame mounted upon suitable wheels, and upon which is pivoted a truck-,platform of suitable construction. The forward end of this platform is connected to the supporting-frame of the deviceby means of rods pivoted together.

f The joint between theserods is connected to va shifting rod having means whereby the same is locked in adjusted position. A trip is provided for releasing the operating-rod from its catch and for throwing the truckplatform into lowered position.

The invention also consists 'in the further novel construction and combination of parts hereinafter more'fully described and claimed, 4and illustrated in the accompanyingdrawings, showing the preferred form of our in vention, and in whichterville, in the county of Kennebec and State Figure 1 isa perspective view of our imthereof, and is connected,'by means of a breakjoint 10 to a rod 11, pivoted to the forward 6o end of the frame 1. An operating-rod 12 extends from the joint 10 and is sldably mounted upon a rod 13, extending transversely of the frame. This rod 12 also extends through a slotted standard 14,'monnted upon the frame, 65 and to the upper end'of which is secured a spring-catch 15,which normally contacts with the upper edge of the operating-rod. An L- shaped trip 16 is pivoted within the slotted4 standard 14 at a point` below the rod 13', and 7o one member 17 thereof is normally horizontal, while the opposite member 18 is adapted to extend upward yin front of ay toe 19, extending'downward from the rear end of the operating-rod 12. The spring-catch 15 is adapted 75 to engage a recess 20formed within the upper edge of the operating-rod 12, and hold said rod in position when the same is pressed for.- ward to the limit of its movement. Oppositely-extendng lugs 21 are arranged at the 8o forward end of the operating-rod 12'and are adapted to limit its forward movement by coming into contact with the two pivoted rods 9 and 11, respectively.

When it is desired to swing the truck-plat- 8 5 form for the purpose ofv placing a trunk or other article thereon, the member 17 is depressed in any suitable manner and the member 18 of the trip will force the toe 19* and its rod 12 backward, at the same time automat- 9o ic'ally forcing the spring 15 out of recess 2'0. This movement of the rod 12-wi'll draw the joint 10 backward and fold the rods 9 and 11 upon each other, thereby bringing the parts into the position illustrated in dotted lines in 9 5', Fig. 2. In order to .raise 4the platform, it isl merely necessary to pull down the handles 8. This will cause the rods 9 and 11 to straighten ,and draw the rod 12 forward. As the member 1,8 of the trip -16 is at all times in the path Ioo of the toe 19, it will be contacted by said toe when the rod 1 2 is moved forward and move .'.to its original position. The notch or recess will also be engaged by-spring 15, andthe .parts will thus be locked in position.

. It' desired, the truck may be provided with 'foot-operated means for assisting inthe hoisting of the truck-platform to its original -position. Whenmhis additional hoistingvdevice is employed, brackets 22 are secured to the otedt'otheinner Sacos of the lower ends of standards'fli and. are provided at ,their forward ends withrollers 2'6',yvhi1e their rear ends are l fam connected by means of a transverse section 27.

Having thus fully described the invention,` what is claimed as new is'- to permit rollers 26 .to move upward the de- As shown in dotted lines in Fig. 2,wh'enthe trunk-platform is tilted downward the inclined faces of brackets 22, will hearl upon the rollers 26. to raise the platform, the handles 8 are drawn downward, and at the same time the connect-y ing-section 27 of levers 25 is pressed downward by the foot of the operator. Rollers 26 will then force the forward end of thevplatfV form upward.

' .In the foregoi'ngdescrptio'n we-ha'veshown the preferred form of our invention; but We do not limit ourselves thereto, as we are awarethat modifications may be lnade therein without departing from the spirit or sacrificing any of the advantages of the invention, and we therefore reservet he right to make all such changes as may fairlyfall '1.
